【摘要】 通过引进观赏价值高的大花萱草品种，在西湖景区营造大花萱草特色植物景观，建立西湖景区大花萱草应用推广评价体系，选育适合西湖景区园林绿化的萱草品种，为大花萱草在江浙地区的应用推广提供理论依据。基于对大花萱草生物学和生态学研究，以观赏和应用价值为目标，确立12个评价因子，采用层次分析法(AHP法)建立大花萱草综合评价模型。按照综合评价模型，对28个大花萱草品种在杭州西湖景区的表现进行综合评价，筛选出9个表现优良的大花萱草品种。通过对大花萱草连续3年(2018—2020年)的观测，结合生态习性探讨其在西湖景区的园林应用价值，并提出相应的栽培技术和病虫害防治要点。更多还原

【Abstract】 The characteristic plant landscape of Hemerocallis hybridus will be created in Hangzhou West Lake Scenic Area by introducing varieties of Hemerocallis hybridus with high ornamental value. The application and promotion evaluation system of Hemerocallis hybridus will be established, and Hemerocallis hybridus varieties suitable for landscaping will be selected in Hangzhou West Lake Scenic Area, which provide a certain basis for the application and promotion of Hemerocallis hybridus in Jiangsu and Zhejiang regions.Based on the study of biology and ecology of Hemerocallis hybridus, 12 evaluation indexes were established for the purpose of ornamental and application value. Analytic hierarchy process(AHP) was used to establish the comprehensive evaluation model of Hemerocallis hybridus.According to the comprehensive evaluation model, 28 Hemerocallis hybridus in Hangzhou West Lake Scenic Area were judged by this way and 9 varieties with excellent performance were obtained. Through the observation of Hemerocallis hybridus during 2018-2020, combined with ecological habits, its garden application value in Hangzhou West Lake Scenic Area were discussed.
